Flashcards helpful for
|Cell Cycle and Cell Division||
Cell Cycle and Cell Division
|Interphase||The phase between two M (mitosis) phase, >95% of cell cycle
G1, S and G2
|G1 phase||Cell is metabolically active and grows
|S (synthesis) phase||DNA Replication
Chromosome number remains the same, DNA amount doubles
Synthesis of histone proteins
|G2 phase||Protein synthesis for mitosis|
|M (Mitosis) phase||Equational division
Karyokinesis- Prophase, metaphase, anaphase, telophase
Centrosome move to opposite poles
ER, Golgi bodies, nucleolus and nuclear envelope disappear
|Metaphase||Sister chromatids visible, chromosomes are studied at this stage
Spindle fibres attached to kinetochore present at centromeres
Chromosomes get aligned at the equator
|Anaphase||Sister chromatids split and move to opposite poles|
|Telophase||Chromosomes lose their discrete identity and form clusters
Nuclear envelop develops around each cluster forming daughter nuclei
Nucleolus, ER, Golgi complex reappear
|Cytokinesis||Mitochondria, plastids, etc. get distributed in daughter cells.
In plants, wall formation starts in the middle as cell-plate.
Furrow method in animal cells.
|Syncytium||Multinucleate cell resulting from absence of cytokinesis after karyokinesis.
E.g. Multinucleate, liquid endosperm in coconut
|Meiosis||Meiosis I and meiosis II
DNA replication only occurs once.
Chromosome number is halved in daughter cells
|Zyogotene||Pairing of homologous chromosomes
Synapsis and formation of synaptonemal complex
Bivalent or tetrad chromosomes
|Pachytene||Crossing over and recombination|
Can last up to years in vertebrate oocytes.
|Anaphase I||Separation of homologous chromosomes
Sister chromatids remain attached
|G0 (quiescent stage)||Inactive stage after G1, in cells that do not divide frequently, e.g. heart cells|
